SHAFT-'TUG.

SPECIFICATION forming part of Letters Patent No. 808,999, dated December 9, 1884.

Application filed February 1,1884. (No model.)

To aZZ whom it may concern.-

Be it known that we, ALLEN 0. SMITH and RICHARD J. DIEHL, citizens of the United States, residing at Bethlehem, in the county of Northampton and State of Pennsylvania,

have invented certain new and useful Improvements in Shaft-Tags, of which thefollowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in shafttugs, and has for its objects to prevent the shafts from sticking in the tags when the horse is removed from the vehicle, to prevent accident; also, to allow the shafts to slide freely back and forth therein, whereby the horse is prevented from being chafed by the saddle on the back, eilherin backing or going downhill, as the saddle will remain in its proper place without strain thereon. These objects are attained by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a perspective view of a shafttng provided with ourimprovement. Fig. 2

is a detached view of a metal frame, which may be fitted to any of the tugsin general use. Fig. 3 is a detailed view of a roller. Fig. at is a detached view of a metal tube. Fig. 5 is a detached view of a removable flange, taken from one. end of the metal tube shown in Fig. 4. Fig. 6 is a view of a rivet which passes through the roller B and serves as a shaft upon which it turns, and, together with the flanges m, secures the frame to the leather form- Figs. 7, 8, 9, 10, 11, 12, and 13 are views of various modifications of our invention.

At the bottom of the frame A there is a cross-bar, a, which extends across to the flanges a" and forms a loop by means of which the strap L may be attached to the tug.

The frame A is of metal, preferably of malleable cast-iron, but may be made of any other suitable material-such as east-iron, brass, hard rubber, celluloid, or bone. It may be painted, japanned, plated, coated with rubber or other material-such as leather or celluloid.

It may also be cast without the cross-bar a, and the strap L may be attached to the tug by a D or ring of the ordinary shape, fastened to the leather part of the tug that runs over the frame A; and the strap L can be made all in one piece when there is no cross-bar a, and the frame will remain in its place.

The frame A may be cast without any flange 5 5 or any loop, and may yet be adapted to hold' the rollerB. The tube 0 has a fixed flange,

F, and is furnished with three pins, J, which enter holes H in a removable flange, G, and may ,thereby be riveted to the tube after the roller B has been slipped thereon, and thus forms a bushing, upon which it revolves and preserves it from wear. The rollerB ispreferably made of leather, but metal, bone, rawhide, or any other suitable material may be employed for this purpose.

Having described. our invention, what we dcsi re to secure by Letters Patent and claim 1s The combination. in a shaft-tug, oftheframe 0 A. having a cross-bar, a, the strap M, the roller B, and the tube 0, upon which the roller is mounted, the said tube being provided with a stationary and a detachable flange, whereby it is secured in place and the strap held upon the frame, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
